Campuses wanting to be greener may want to give USFI a look. The company offers biodegradable and recycled card stock for IDs. A typical PVC card will take between 200 and 300 years to breakdown in a landfill, where as USFI’s biodegradable cards will turn to dust anywhere from nine months to five years, says Brian Sterling, account executive at USFI Student ID Cards.

USFI’s card stock has an enzyme that begins to break the card down once it’s placed in a landfill. The company also offers recycled cards for campuses to use as well.
